RECTIFICATIF TECHNIQUE 1

Technical Corrigendum 1 to ISO 8062-3:2007 was prepared by Technical Committee ISO/TC 213,

Dimensional and geometrical product specifications and verification

Page 2, Normative references

Replace the reference to ISO 10135:— with the following:

ISO 10135:2007, Geometrical product specifications (GPS) — Drawing indications for moulded parts

in technical product documentation (TPD)

Delete the reference to Footnote 3) and the footnote “To be published (Revision of ISO 10135:1994)”

Renumber the reference to Footnote 4) and the footnote itself to Footnote 3)

ISO 8062-3:2007/Cor.1:2009(E)

Page 13, Table A.3

In table footnote b, replace the words “investment castings” with “pressure die castings”, to give the following:

b For pressure die castings, the following apply:

— Grade GCTG 2: should only be used by special agreement;

— Grade GCTG 3: ordinary castings without side sliders for the contour;

— Grade GCTG 4: complex castings as well as castings with side sliders for the contour.
